JdbcOperationsSessionRepository.jdbcSession is not visible

Question

My program is using Spring Session xml based configuration and I using JdbcOperationsSessionRepository to implement my session. The JdbcOperationsSessionRepository library is using JdbcOperationsSessionRepository.JdbcSession and how can I set the session attributes?

package sessioncontrol.page;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.session.Session;
import org.springframework.session.jdbc.JdbcOperationsSessionRepository;
import org.springframework.session.jdbc.JdbcOperationsSessionRepository.JdbcSession;
import org.springframework.session.jdbc.config.annotation.web.http.EnableJdbcHttpSession;
import org.springframework.stereotype.Controller;
import org.springframework.transaction.PlatformTransactionManager;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

import lombok.extern.log4j.Log4j2;

@Log4j2
@Controller
@EnableJdbcHttpSession
public class SessionControl {
    @Autowired
    JdbcTemplate jdbcTemplate;

    @Autowired
    PlatformTransactionManager transactionManager;

    private JdbcOperationsSessionRepository repository;

    @RequestMapping(value="flpage", method=RequestMethod.GET)
    public String showPage(Model model) {
        repository = new JdbcOperationsSessionRepository(jdbcTemplate, transactionManager);
        repository.setTableName("test.spring_session");
        repository.setDefaultMaxInactiveInterval(120);
        JdbcSession session = repository.createSession();
        session.setAttribute("ATTR_USER", "rwinch");
        repository.save(session);

        return "flpage";
    }
}

It show me import org.springframework.session.jdbc.JdbcOperationsSessionRepository.JdbcSession; is not visible so how can I use the inner class set attribute method properly? I really stuck here.

Thanks in advance, any comment is appreciate.

First off, you should use an interface (either SessionRepository or FindByIndexNameSessionRepository) to interact with your repository and inject the instance that was created by Spring Session configuration and registered as a bean in the application context, rather that instantiating JdbcOperationsSessionRepository yourself.

There are basically two ways you can inject a FindByIndexNameSessionRepository instance - either to inject and use raw type, or parameterized (respecting the original contract of FindByIndexNameSessionRepository<S extends Session>).

Raw type approach:

class RawConsumer {

    @Autowired
    private FindByIndexNameSessionRepository sessionRepository;

    void consume() {
        Session session = (Session) this.sessionRepository.createSession();
        session.setAttribute("test", UUID.randomUUID().toString());
        this.sessionRepository.save(session);
    }

}

Parameterized type approach:

class ParameterizedConsumer<S extends Session> {

    @Autowired
    private FindByIndexNameSessionRepository<S> sessionRepository;

    void consume() {
        S session = this.sessionRepository.createSession();
        session.setAttribute("test", UUID.randomUUID().toString());
        this.sessionRepository.save(session);
    }

}
